   - This is a bit tricky now: The `pointsPerHiresTile` field defines the amount of low-res-points on a low-res-tile that each high-res-tile will occupy. So if the `tileSize` of the high-res tiles is `32` and the `pointsPerHiresTile` is `4`, each low-res-point will contain a `32/4 = 8` -> 8 * 8 chunk of your world. This is why you have to always choose values that result in an integer if you use that calculation!
   - The `pointsPerLowresTile` field is the amount of how many low-res-points each low-res-tile is wide.
   - And finally the `viewDistance` defines the default amount of low-res-tiles the web-app will load at once in each direction. *(The view distance can also be adjusted in the web-app with a slider)*
